Dear Asnys, thank you very much for not using the Orion and the Pluto.
Of course it all depends on the timeframe of your timeline and the type of Cold War that develops there.
If you want to give Britain an early nuclear capability, perhaps this is the bomber for you:

For an alternate American attack helicopter, perhaps the AH-56 Cheyenne should be tried:

For low intensity warfare, the Convair Charger could be used instead of the North American OV-10 Bronco:

Now, these and the following weapons are just suggestions, I am not an absolute fan of them, and perhaps other posters can point out good reasons not to build them.
I think there are some good reasons to leave the Gyrojet rocket pistol and carbine to the film industry: as the Wikipedia article states, it is impossible to load quickly, has much too slow velocity at short range, (usually) lacks accuracy at long range and has severe reliability problems.
And then there is my favourite plane that should have been cancelled, but wasn't:
The Lockheed F-104 Starfighter. Perhaps many of us already know it, but I'll write it anyway. The F-104 was originally conceived as a fairweather interceptor and found only limited favour with the USAF. It was later converted into an allweather, multi-role combat aircraft that saw service with the Belgian, Canadian, Danish, Dutch, German, Italian, Japanese, Jordanian, Norwegian, Pakistani, Spanish, Taiwanese and Turkish airforces (possibly still others). It had limited range, payload and maneuverability and a
very high accident rate. In several countries corruption scandals broke out when it was discovered that Lockheed had given massive bribes to politicians to further the sale of this plane.
So this plane was at one time both extremely widely used in the West and extremely problematic. If these countries have something better than the F-104, I think the position of the West in the Cold War would be substantially strengthened. If you are looking for a replacement, candidates from our timeline should be considered just as much as those that were not mass-produced in OTL. Perhaps almost anything is better than what was used in OTL. Possible suggestions from OTL: Dassault Mirage III (perhaps with a more powerful engine, not neccessarily a French one, perhaps also with canards like the Israeli Kfir), English Electric Lightning, earlier use of the F-4 Phantom outside the US, Vought Crusader. For the strike role Blackburn Buccaneer or TSR.2. "Alternate" candidates: Hawker P.1211 or P.1221 (I am not even sure about the exact designation) or a multi-role version of the Convair F-106 with canards.
If you want more ultra-high speed planes like the SR-71, perhaps the North American F-108 Rapier can be considered, but it is probably uneconomical to have both.
Perhaps it is best to have fewer, rather than more types of weapons mass-produced, especially as fighter planes in the Fifties are concerned. Large production runs are more economical than small ones, and it is easyer to maintain an inventory of spare parts for a few types of machines than for many, though apart from the F-104 mentioned above, I do not know where the axe should be used.
I am looking forward very much to your timeline.
Just one more small thing: If at all possible, try to keep the Earth in one piece.
Thank you very much in advance.
